File with ACSM extension contains binary data for activating and downloading an ebook, for example, eBooks with Adobe Content Server in Adobe Digital Editions software.
Files with the EPUB extension contain electronic publications - Electronic PUBlication, compressed with ZIP compression method, stored in an open format based on XML. Within the file, there is also some metadata on a given publication. It also enables to search through the text for specifics.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the ACSM file after converting to EPUB may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from ACSM to EPUB to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting ACSM to EPUB does not meet your expectations, you can simply try to find on the Internet a different version of your file in ACSM format, properly converted to a EPUB file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file ACSM the desired result was not achieved, you can try to change the format of ACSM file to other than EPUB. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your ACSM file converted by someone else, and the attempt to convert it to EPUB on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the ACSM file in its original format (without conversion to EPUB file). Such a solution will be difficult to implement, but it certainly will give the best result.
