1. How long do you support users of the previous versions and provide free updates?
We warrant lifetime support and lifetime free updates for all v1.0 - 1.5 buyers.
However we reserve the right to change this policy for buyers of later versions.
2. The program doesn't view some AI files. Why?
The app v1.0-1.2.2210 displays the built-in thumbnails for AI v7-CS2 and AIT v10-CS2 files only.
The built-in thumbnails in AI files appeared since version 7. However, some v7-CS2 files don't contain the built-in thumbnails.
Usually such files are exported from other applications (e.g. CorelDRAW).
If you have Adobe Illustrator 10-CS3 you can use our free batch converter.
It can transform the files of any version which can be opened in your Illustrator to files v7-CS3 with built-in thumbnails.
The app v1.2.2220+ displays the built-in thumbnails for AI v7-CS3 and AIT v10-CS3 files (v1.2.2300+ can display the built-in thumbnails
for AI/AIT CS4-CS6 too). Except the built-in thumbnails in AI7 format, the program can display the built-in thumbnails in AI CS2+ format.
Thumbnails in AI CS2+ format have the sizes up to 256x256x24 (larger than old thumbnails in 4 times).
These thumbnails can contain in AI v9+ and AIT v10+ files saved from Adobe Illustrator CS2+.
STTEX v1.5 Beta 5 can show magnificent (up to 600x600 pixels) thumbnails
for AI (and AIT) files all versions (including CS4-CS6) by using CorelDRAW 12+, Corel DESIGNER 12+, and/or Ghostscript.
Ghostscript is free for end users, CorelDRAW 12+ and Corel DESIGNER 12+ are commercial products.
With Ghostscript, STTEX 1.5 Beta 5 can display generated thumbnails for AI files v7-CS6 (the files v10-CS6 must be PDF-compatible).
Nevertheless, PDF uncompatible files v10-CS6 and all AIT files will not be displayed (the app will display the built-in thumbnails only).
With CorelDRAW 12-X4 or Corel DESIGNER 12+, the app can display all types of AI files up to AI CS2 and AIT v10-CS2 (with CorelDRAW X5/X6 - AI/AIT CS3-CS4 too)
without any conversion, and save the generated thumbnails to the app database
(Note: Unfortunately, some files CorelDRAW/DESIGNER engine cannot process. Particularly, the engines cannot process all files having the version
exceeding N-1, where N - the version of installed engine).
Without use of any external engines, v1.5 Beta 5 can display the built-in thumbnails in all formats for all AI/AIT v7+.
3. My ST Thumbnails doesn't view some EPS files. Why?
Please upgrade ST Thumbnails to v1.5 Beta 5. This version displays any pixel-based EPS files
and embedded previews/thumbnails (if they exist) for others (general postscript) EPS files.
You can use our free batch converter to convert any EPS files to a displayed form.
Besides, if you install Ghostscript (it is free for all end users),
v1.5 Beta 5 will display all EPS files.
If Ghostscript v7.00+ (except Ghostscript v8.70 which has bugs in API used by STTEX) is installed and some EPS files not are displayed properly,
your files are wrong/corrupted with very high probability.
4. I want to see all pages of the PDF files. My ST Thumbnails show the first 10 pages only. Can it be corrected somehow?
Of course. Please click in the app main menu Tools|Options|File Formats and enter "0" into the field
"Multi-page mode: Extract up to XX thumbnails for PS/PDF files"
(this setting determines viewing of PRN files too).
Besides, you should set the mode "Display All File Pages" on the toolbar.
5. I would like to know why my ST Thumbnails 1.2 doesn't read CPT files.
Probably you use ST Thumbnails of version 1.2.2135 or lower:
- V1.2 - 1.2.2135 display CPT thumbnails only if Corel Thumbnails Handler shell extension is installed.
- V1.2.2140 - 2500 display the built-in thumbnails for CPT files v7+,
and generates thumbnails for CPT files v5-6 without use of Corel Thumbnails Handler.
- V1.5 Beta 5 can render all versions CPT files without using any Corel software.
However, it does not support Corel PhotoPaint effects and some types of transparency masks.
Besides, this version can use installed CorelDRAW 10-X6, Corel DESIGNER 12-X5, and/or Corel WordPerfect 12-X6
to generate the big quality CPT v7+ thumbnails.
Please refer to CPToptions.reg file in the app install folder for additional info.
6. My ST Thumbnails doesn't view CorelDRAW X4 CDR files. Will you support these files?
Corel uses new file structure for CDR, CDT, PAT and CSL files in CorelDRAW Graphics Suite X4.
Some changes have been made in CPT file structure too.
Currently the app already supports CorelDRAW X4 CDR, CDT, PAT, CPT, CSL v.5.0, and Corel DESIGNER X4 DES files
(BTW, v1.2.2500/v1.5 Beta 5 supports CorelDRAW X5-X6 files too).
It does not require CorelDRAW/DESIGNER X4 installation. Therefore, please update your STTX version up to
1.2.2500 and/or STTX 1.5 Beta 5
(or newer if it is available).
For these formats, the app provides displaying of the thumbnails for all file pages, displaying the metadata (keywords, notes,
fonts, etc.) and entire file texts (up to 20 first strings maximally).
7. ST Thumbnails 1.2 doesn't display CGM thumbnails. That would sure be a great one to add.
V1.5 Beta 5 can use external engines (currently CorelDRAW 10+, Corel DESIGNER 12+, Corel WordPerfect 12+, Ghostscript 7+,
and MS Office 2003+ Document Imaging) for thumbnails extract (please note, external engines are used
in the "External Extract" mode only).
If CorelDRAW 12+/DESIGNER 12+ is installed, v1.5 Beta 5 can generate thumbnails for CGM files (and then display these thumbnails for all modes).
Besides, with CorelDRAW/DESIGNER/WordPerfect engine, this version can generate thumbnails for the following formats:
CDR, CMX, CDT, PAT, CCX, CLK, AI,
AIT, FH7, FH8, FT8, CPT, DES, CSL, DSF, DRW, DS4, WPG, CPX, CDX, SVG, SVGZ,
PCT, PICT, DXF, DWG, PLT, HGL, FMV, GEM, PIC, VSD, MET, NAP, PPF, FPX, SCT, CT, IMG, PP4, PP5, MAC, CAL, WI, WVL, XPM, XCF,
RIF, SHW and some others. (Please note, some listed formats cannot be supported by the installed CorelDRAW/DESIGNER/WordPerfect version.
Besides, the installed engine can process not all files of the given type).
Since v1.5 Beta 3 the app can use the third-party plug-in CADImage.dll
to generate quality thumbnails for CGM files (BTW with this plug-in, the app can generate quality thumbnails for many CAD formats:
DXF, DWG, PLT, HGL, HPGL, SPL, SVG, etc.).
Currently this feature is not provided by default, you can add the feature with CAD_Formats.reg (this file is located
in the app install folder, please edit the file (enter correct CADImage.dll path) before merge the file with the system register.
8. Will your program suggest keyword-based search for CDR, CMX, CCX, etc. files?
Since v1.5 Beta 2 the app provides Quick Search feature. This component provides the search for keywords,
notes, other metadata in XMP, IPTC, Exif, and Adobe IRB metadata sets, just as on entire file text for
CorelDRAW 7-X6, Corel DESIGNER 10-X5, MDI, MS Office 2000+, MS Visio 2000+, HTML, plain text, and some other file types.
BTW, the search is possible and on offline CD/DVD disks too.
9. Can your software support CRW RAW files?
Unfortunately currently the app does not support CRW RAW files. However, we plan to support native
formats for many cameras within the nearest months (including Canon RAW CRW files).
10. Can your app support DDS files?
STTEX can display Dynamic Daylight Simulations (DDS) files,
if DDS Viewer is installed. DDS Viewer is free Shell extension from NVIDIA Corp.
You can download this app from
The size of DDS thumbnails up to 300x300 pxs.
